It looks like the dates to Superman, Vol. 4 #1 are off. They list 2022 but I think most should be 2016.
I think 1A and 1B should have a cover date of August 2016 (and a release date of June 15, 2016, according to DC’s page).
The second printing (1C) has a cover date of September 2016.
I don’t own the others and so can’t help wotb those…. thanks!
